  • the possibility of changing the resonance frequency is particularly useful, as it allows the transducer 3D to change its resonance frequency not only due to construction tolerances but also in response to various environmental factors, such as mud, humidity, dust, water, plant residues, etc.
  • the microcontroller of the remote element 3 will emit frequencies, within the range of resonance frequencies of the transducer 3D, that are pleasant or unpleasant for the controlled individual, or are more less audible for the user (the latter being selected by the user via a keypad, preferably a membrane keypad, which is also used to turn the remote element on and off, or via a remote control that will be described below).
  • Such voltage measuring circuit may consist of a resistor that picks up the voltage from the transducer 3D and whose voltage is rectified, detected and presented to the microcontroller 3B of the remote element 3 through the analog-to-digital converter.
  • the microcontroller 3 B of the remote element 3 controls the transducer 5 by performing a quick frequency scan to search for that resonance frequency with the purpose of tuning the control signal frequency with the resonance frequency of the transducer.
  • Automatic tuning of the circuit for measuring the current of the transducer 3D with one of the resonance frequencies of the transducer 3D may be alternatively performed using a method that uses the response to an impulse.
  • the transducer 3D may be excited with a very short impulse, for later measurement of voltage drop time at the ends of the transducer (or of the control transformer, if any) by an analog-to-digital converter.
  • This method is adequately reliable and quick and does not involve the emission of undesired sounds from the transducer in addition to the short impulse.

Abstract

L'invention concerne un appareil de détection de mouvements (1) et/ou d'entraînement d'un individu comprenant: un collier (2) muni d'un élément électronique distant (3) et pouvant se poser autour du cou ou de la taille de l'individu à entraîner ou dont l'état est à détecter, ledit élément électronique (3) comportant: un accéléromètre ou un détecteur de vibrations similaire détectant l'état de l'individu suivi, un microprocesseur, un premier émetteur/récepteur et un transducteur acoustique (5), une télécommande manuelle (4) comportant un deuxième émetteur/récepteur et un microprocesseur, interconnectés. Ledit élément électronique distant (3) et ladite télécommande (4) établissant une communication bidirectionnelle pour émettre et recevoir des signaux contenant des données codées, respectivement émis et reçus par le premier émetteur/récepteur et le deuxième émetteur/récepteur. L'appareil se caractérise en ce que le microcontrôleur (4B) de ladite télécommande (4) est conçu pour détecter la distance séparant l'élément électronique distant (3) de la télécommande (3) en mesurant l'intensité du signal émis par l'élément électronique distant (3) et reçu par le deuxième émetteur/récepteur (4A) de la télécommande (4), ladite communication se faisant par RF sur une plage allant de quelques centaines de MHz à un maximum de 2,5 GHz, et la valeur des mètres linéaires couverts par la télécommande (3) entre des instants successifs étant une fonction de la courbe accélération-temps de la télécommande (3), ladite accélération étant détectée par l'accéléromètre (3A) de l'élément électronique distant (3).
